Cheapest TB-500 5 mg

27 vendors that pass our metascore cutoff (70+) list TB-500 in 5 mg vials with a current, in-stock price. The lowest price per milligram is USD 1.40 at Huaian Dinglin Trading (10 × 5 mg = 50 mg for USD 70.00); the lowest total at checkout is USD 19.36 at Bio Pepz (1 × 5 mg). Cheapest is not the same as best: the metascore beside each vendor sums up independent lab tests of vials bought like a customer would, whether its own lab reports hold up and whether its claims match what buyers measured. Affiliate links never change the order.

Prices last checked 13 Nov 2026 (oldest on this page: 9 Nov 2026). Shipping is not included.

Cheapest TB-500 5 mg: questions

What is the cheapest 5 mg TB-500?

Per milligram, Huaian Dinglin Trading is cheapest right now at USD 1.40 per mg (TB500(Thymosin B4 Acetate) 5mgx10vials, 10 × 5 mg = 50 mg, USD 70.00). The lowest total at checkout is Bio Pepz at USD 19.36 for 1 × 5 mg. Both come from 27 vendors with a current, in-stock 5 mg price.

How much does a 5 mg vial of TB-500 cost?

Across 27 vendors, a 5 mg vial works out to $7.00 to $78.00 (median $31.19), counting kits by their price per vial. Shipping is extra at most vendors and is not included.

Is a TB-500 kit cheaper than single 5 mg vials?

The cheapest kit here is USD 1.40 per mg (Huaian Dinglin Trading, 10 × 5 mg = 50 mg, USD 70.00 in total); the cheapest single vial is USD 3.87 per mg (Bio Pepz, USD 19.36). A kit is only cheaper if you will use every vial before it expires.

Which listings are left out?

Vendors below a metascore of 70, vendors you can only order from by message, listings marked out of stock, prices older than 14 days, and prices far outside the range other vendors charge for the same peptide (usually a vial-count mistake or a whole kit priced as one vial).

How current are these prices?

Prices are read from each vendor's own website; the newest on this page was checked on 13 Nov 2026. The page is rebuilt with every price refresh, and a listing drops off once its price is more than 14 days old. Check the vendor's page before ordering.

Do affiliate links change the ranking?

No. The tables are sorted by price only. Some Buy links are affiliate links that may earn PeptideCompare a commission at no extra cost to you.
